Yes matches are bi-directional, but the match is at the higher tiered user's discretion. That is, by paying more, you have the option to more finely filter matches. Regarding ethical concerns, I'm not imagining tiers in the hundreds or thousands of dollars, but something like a one-off $1, $10, $20 payment wouldn't be segregating by social class in any significant way while still providing nominal filtering ability.
